The standard is the European specification for threaded pipe fittings manufactured from malleable cast iron . First published in 1995 to harmonize European piping requirements, it replaced older national standards like BS 143 and BS 1256 for most common fitting types. A PDF of this standard provides technical guidelines for the design, material composition, and performance of these fittings used in the transmission of fluids and gases. 1. Scope and Application

Tensile testing is performed on separately cast test bars or samples taken from the fitting to verify the tensile strength and elongation properties promised by the grade designation. BS EN 10242 The standard is the European
Compliance with BS EN 10242 is not merely a regulatory checkbox; it is a matter of operational safety. A failure in a threaded fitting can lead to: Compliance with BS EN 10242 is not merely
It is vital to understand that (for heavy malleable iron fittings) and BS 1256 (for light malleable iron fittings) have been withdrawn and replaced by BS EN 10242. However, many legacy systems still reference the old BS numbers.
